310 DESCRIPTION OF PLATES. 



PLATE IV. 



FIG. 1, exhibits a Back View of the Fore-arm and Hand. 

 The Preparation from which this View was taken having 

 been previously dried, the Muscles appear very slender. 



A, The hand. 



B, The lower extremity of the radius, 

 c, The lower extremity of the ulna. 



D, The muscles on the back of the fore-arm turned aside 

 to exhibit a deep-seated lymphatic vessel, which perforates the 

 interosseous ligament to get to the fore part. 



E, The olecranon. 



On the Outlines. 



a, 0, a, Lymphatics appearing on the back of the fore-arm, 

 immediately under the skin. 



b } Some of the lymphatics bending over the upper extremity 

 of the radius to get to the fore part of the arm. 



c, A lymphatic passing over the ulna, immediately under 

 the olecranon, and under the inner condyle of the os humeri, 

 to get to the fore part of the arm. 



d t A lymphatic which has penetrated the muscles, perforates 

 the interosseous ligament, and gets to the fore part of the arm 

 near the radial artery. 



FIG. 2, exhibits a fore View of the upper Extremity. This 

 Plate was likewise made from a dried Preparation, and 

 the Muscles therefore appear very small. It has a 

 peculiarity in the ulnar artery running over the muscles 

 instead of under them. 



A, The scapula. 



B, The clavicle. 



c, The extremity of the brachial artery. 



D, The muscles lying on the inside of the arm.
